Abstract

The present application relates to the field of household appliances, and in particular to a locking assembly, a drawer assembly and a storage cabinet. The locking assembly includes: a mounting member, a locking member rotatably connected to the mounting member and configured to be switched between a locked state and an unlocked state, and the locking member includes a locking portion and an unlocking portion; in the locked state, at least part of the locking portion is located at a motion path of a to-be-locked member and the unlocking portion is located at an avoidance path of the to-be-locked member; and in the unlocked state, the locking portion is located at the avoidance path and at least part of the unlocking portion is located at the motion path.

What is claimed is: 
     
       1. A locking assembly, comprising:
 a mounting member; 
 a locking member, rotatably connected to the mounting member and configured to be switched between a locked state and an unlocked state, wherein the locking member comprises a locking portion and an unlocking portion; and 
 an elastic member, having a first end rotatably connected to the mounting member and a second end rotatably connected to the locking member; wherein 
 in the locked state, at least part of the locking portion is located at a motion path of a to-be-locked member and the unlocking portion is located at an avoidance path of the to-be-locked member, and 
 in the unlocked state, the locking portion is located at the avoidance path and at least part of the unlocking portion is located at the motion path, and the elastic member is in a compressed state to make the locking member be stuck. 
 
     
     
       2. The locking assembly of  claim 1 , wherein the mounting member comprises a guide groove, and
 the elastic member, having the first end fixed to a bottom wall of the guide groove and the second end slidably matched with the guide groove; 
 a state switching member, having an end rotatably connected to the second end and another end rotatably connected to the locking member. 
 
     
     
       3. The locking assembly of  claim 2 , wherein the locking member is connected to the state switching member at a first point of rotation, the locking member is connected to the mounting member at a second point of rotation, the state switching member is connected to the elastic member at a third point of rotation; the locking member is configured to be switched among the locked state, a critical state and the unlocked state. 
     
     
       4. The locking assembly of  claim 2 , wherein in the locked state, the elastic member is in a deformed state. 
     
     
       5. The locking assembly of  claim 1 , wherein the mounting member comprises a mounting housing and a mounting base,
 an inner wall of the mounting housing defines a mounting cavity in which the mounting base is located, and the locking member is rotatably connected to the mounting base, 
 in the locked state, at least part of the locking portion stretches out of the mounting cavity and the unlocking portion is located in the mounting cavity, 
 in the unlocked state, the locking portion is located in the mounting cavity and at least part of the unlocking portion stretches out of the mounting cavity. 
 
     
     
       6. A drawer assembly, comprising:
 locking assemblies of  claim 5 ; and 
 a lifting platform 
 wherein a number of the locking assemblies is two, and the two locking assemblies are located on left and right sides of the lifting platform, respectively, 
 outer side walls of both the mounting housings together define a lifting space, the lifting platform is liftably provided in the lifting space and configured to be switched between a suspending state and a free state, and 
 the lifting platform comprises a locking groove, and at least part of the locking portion matches in the locking groove in the suspending state. 
 
     
     
       7. The drawer assembly of  claim 6 , wherein a bottom of the lifting platform comprises a reset member,
 the reset member is configured to push the locking portion or the unlocking portion during the lifting and lowering of the lifting platform, to make the locking member switch between the locked state and the unlocked state. 
 
     
     
       8. The drawer assembly of  claim 7 , wherein the reset member comprises a reset plate or a reset roller. 
     
     
       9. The drawer assembly of  claim 6 , wherein an inner drawer for storage is provided on the lifting platform and is configured to be lifted and lowered as the lifting platform is lifted or lowered. 
     
     
       10. A storage cabinet, comprising:
 the drawer assembly of  claim 6 . 
 
     
     
       11. The locking assembly of  claim 1 , wherein the mounting member comprises a mounting base, and the locking member is rotatably connected to the mounting base. 
     
     
       12. The locking assembly of  claim 1 , wherein the locking member comprises a manipulator,
 the manipulator is configured to drive the locking member to switch from the locked state to the unlocked state, and the mounting member comprises an operating hole for the manipulator. 
 
     
     
       13. The locking assembly of  claim 1 , wherein
 one of the locking member and the mounting member is provided with a cushioning member, and 
 the cushioning member abuts against the other of the locking member and the mounting member in the locked state.
